I put it in the PC & it was detected as 2.0 TB HDD in Disk Management.

It also asked me to initialize the disk either as MBR or GPT Partition.

I am using Dell T-7500 Workstation with Windows -7 ( 64 bit ) OS

Can you please help me with following questions :

(1) What should I do to get full 3.0 TB Space rather than 2.0 TB it shows now ?

(2) Should I initialize it first if I want to install Win-7 on it OR just Pop in the Win-7 DVD & start installing it & it will guide me thru the rest of the procedure & help me select MBR or GPT then ?

(3) What should I do if I just want to have Large 3.0 TB single partition ? Should I initialize it & which one, MBR or GPT ?

(4) What should I do in case I initialize it either as GPT or MBR & don't get full 3.0 TB Of Space ?
